使用aspnet\u merge的VSTS生成导致错误“无法在应用程序级别下定义元素‘buildProviders’”

当我建立我的asp。net应用程序在VST中与aspnetcompiler一起出现在msbuild参数或发布配置文件中,我得到以下错误:

MyProject\obj\release\aspnetcompilemerge\source\web.config(129,0): Error ASPCONFIG: The element 'buildProviders' cannot be defined below the application level.
Process 'msbuild.exe' exited with code '1'.

我相信这是指web.config的这一部分:

<buildProviders>
    <add extension=".rdlc" type="Microsoft.Reporting.RdlBuildProvider, Microsoft.ReportViewer.WebForms, Version=14.0.0.0, Culture=neutral, PublicKeyToken=89845DCD8080CC91" />
</buildProviders>

但有两件事很奇怪-

2) 构建似乎成功了。我可以下载工件并将其部署到一个on-prem web服务器上,并且输出似乎已经按照我的发布配置文件中的定义进行了合并。

如何解决这个问题?

编辑-我能够在一个新的MVC项目中再现这种情况。

<MvcBuildViews> csproj文件中的节点。那是什么时候 true ,我收到此错误消息。如果我设置为 false ,构建成功。
